NL Central Notes: Cubs, Rizzo, Cardinals, Lee, Heisey

Cubs GM Jed Hoyer wants to add more depth to his pitching staff, reports MLB.com's Carrie Muskat. "At this point, we're still very much in the process of gathering as many quality arms as we can, and we'll put those pieces in place as we get closer to Spring Training," Hoyer said. "We have worked hard, and we continue to work hard, and hopefully we'll have even more starting-pitching acquisitions….We want to go seven, eight, nine deep in the rotation and we hope to replenish the bullpen as well."

The Cardinalsannounced Derek Lilliquist will become the team's new pitching coach, with Dyer Miller taking Lilliquist's old job as bullpen coach. The moves may or may not be permanent as former pitching coach Dave Duncan is on an indefinite leave of absence to be with his wife, who underwent brain surgery last August.

The Pirates have shown some interest in bringing back Derrek Lee but "the first baseman doesn’t seem to have reciprocated that interest," writes MLB.com's Jenifer Langosch. Of the five remaining Pirate free agents, Langosch thinks only Paul Maholm has a chance of returning, but the Bucs will likely be outbid by one of Maholm's several other suitors.
